Hello again ooppee,
sorry to forgot this in my previous post:
Also the explob.bsp has been done by the same artist.
I am 95% sure it was Ruohis. It fits his style very much.
As far as I see you use the diffuse + gloss skin textures from Rygels pack for your version.
(I am not sure who made them)
May I suggest 2 things:
1.) If you make the hazard symbol on a plane extra surface for the explob.bsp model,
I guess it would look better. (like Ruohis did it)
2.) Your normal has the "bulge" / protrude to the wrong direction ?
I think the rivets should protrude, as it would be realistic.
You used a negative "Intensity" setting in CrazyBump for your normal.
Maybe a positive "Intensity" setting fits the rivets better,
as they would protrude then.
But thats just a personal opinion. I had the same discussion with kingennio.
My-Key also agreed on it.
Anyway you did a great job ooppee !
Another way to achieve it, if you used the "left" shape proposal at the beginning:
Klick on "Invert shape recognition".
Or use the "right" shape proposal at the beginning.
